E 1 I This invention relates to machines for winding webs of flexible material into rolls.

vWeb-winding machines commonly employed have two surface winding rollers rotatable in the same direction and spaced apart for supporting a core or a winding shaft in the valley between the rollers. f lAs the Winding rollers rotate they frictionally engage the surface of flexible material on the Winding shaft and cause the shaft to rotate .and a roll of material to form. A rid- 6 Claims. (Cl. 2425-456) ing roller rests upon the roll of material and rises u. y

as the diameter of the roll increases during a winding operation. The path of movement of the riding roller is determined by a pair of arms which extend from a pivot shaft and carry the bearings for the roller. The riding roller is part of a weighted system which is eiective on the pivot shaft and causes the riding roller to exert pressureon the roll. of material. Means are provided for lifting the riding roller from a completed roll of material and after the roll has been removed from the machine and a fresh winding shaft has been placed the riding roller is lowered for another winding operation.

These lifting and lowering operationsheretofore have been accomplished under manual control by the use of a foot treadle and linkageconriecting the treadle with the pivot shaft.v The use of a mechanical connection of this kind requires care for assuring that the ridingjroller system will not inadvertently slip and permit-fthe riding roller to fall and damage itself orvthe winding. shaft, or Acruslrthc operators `iingers. Theriding roller `is relatively heavyV and its', ,ma nipulation by an operator incident to each 4,vs/'inding operation tends to tire the operator andv decrease his eiciency. It is among the objects o f the invention toy conserve thev energy of an operator by providing a winding machine whichrelieves the operator of the necessity yof manually `'elevating the riding rollerbetween windingoperations and of .respon- Vsibility for .the careful lowering of the riding roller Wherebyto eliminate the probability of damage, and accidents due to a falling 'riding roller. The mechanism whereby these and other.object ives are attained involves the use of a reversible motor which drives a one-way clutch through speed reducing mechanism andv in which the clutch is connected for rotating the pivotshaft to lift or elevate the ridingY roller when the motor is operated in one direction. Withy this mechanism the riding roller maybe raised to an elevated position which is determined by a switch whereby the operation of the motor is automaticthe principle ofthe invention.A

jliig` 2 is an elevational'view taken ally discontinued. In view of the irreversible driving characteristics of the gearing of the speed reducing mechanismi and the drive connection of the one-way clutch, the riding roller is held-in the elevated position Without danger of dropping when the operation of the motor is discontinued.

When it is desired to lower the riding roller onto theA material on the winding shaft it is necessary only that the operator reverse the operation of the motor andthereby permitthefpivot .shaft to rotate in the reverse direction as'the j riding roller descends under the pull of gravity. .The descent of the riding roller is accomplished at a sufliciently low velocity to prevent damaging the roll of material, and it is indifferent` as to whether the motor continues to operate after .the riding roller comes into contact with the'roll jof' materialA because. the clutch 'permits the drivu.-l ving shaft lt o over-run the pivot shaft, With-this ,arrangement the riding roller freelyjrests'upon the roll of material under the pull of gravity provided by the riding rollersystem, and the riding .roller may be raised by hand either duringa ing webs of material 'greatly varying in physical characteristics, and'to wind such materials into rolls of desired compactnes's.

The motor is automatically stopped when the rid- -lng roller reaches a predetermined position. This is" accomplished by the opening` of the motor switchZ; 'I'hemotor switch is mounted on the frame' of the'machine at a place adjacentthe Icollar 51 which rotates with the pivot shaft 42 (Figs. =1,'3 and 6) The iopening of the switch is controlled by a cam 63 whose position is circumferentiallyv settablev around the collar 51V by a Vbandl". The band 'and cam'cari be clamped in any desired position by the bouts, Fig. 6. 1As the cam 63 is rotated counterclockwise, Figs. 3 and=6,`jit comes-into. contact with a follower 6B. The follower is carriedLby a pivoted switch- `engaging member 61 which is rocked by the cam "to openj the switch 62 when the riding roller 20 .has been raised a desired amount.

" vIt;isi-fimportant that the pressure rwhich the 'riding-roller 20 exerts on theroll of material be controllable. The pressure of the riding roller '20 is'ladjustable so as tov enable'the winding of material of different kinds' and for producing rolls ofthe same material for 4different uses.

" The pressure of the riding roller is a function of theresultant moment which is exerted on the pivotfshaft 42. This moment is affected by the riding roller 20, the arms 36, 39 and 40, and by other`devices which are secured to the pivot shaft `and 'collectively referredV to as'the pivot shaft systerr'ill In the present winding machine this "system-includes a pair Vof arms 68 and 69 and a rod extending therebetween. The arms 68 and 69 are spaced apart and are symmetrically located with respect to the bearings 1| and 12 of the pivot shaft 42 and the arms 39 and 40 of the riding roller 20 so asto effect distribution of the tortionalv strains in the pivot shaft.

" 1 The rod 10 may assume any suitable form. It is provided at its ends with screws 13, 14, which extendthrough slots and 16in the respective arms. to the Taxis of the pivot shaft 42. The moment caused -by the weight of the rod 10 may be varied by moving the rod along lthe slots and by clamping itfto the arms in the location desired with the resultant moment of the pivot shaft system by which the riding roller is pressed against the surface of the roll of material, depending upon the located position of the arms. When a very tight center or a hard package is desired, the arms r66 and 69 and the rod 10 may be swung to a position across the axis of the shaft42 and towards the winding rollers so as to add their moment to the moment of the riding roller 20 and its assoelated arms. When the desired resultant moment is obtained, the arms are clamped to the pivot shaftt42 by the bolts 11 and 18. In addition to the radial and angular adjustability of the distribution of weight thus obtainable, further refinement of adjustability may be obtained by selecting a rod 10 from a graduated series of similar rods of different weights. This construction is particularly advantageous for adapting a ma- The slots extend laterally with respect 6 v chine'for winding many different kinds of materials.V
